  THE MANURING OF LAND.

  The proper method of manuring is here a very important subject for consideration — we have already treated of it at some length in the preceding Book. The only point that is universally agreed upon is, that we must never sow without first manuring the ground; although in this respect even there are certain rules to be observed. Millet, panic, rape, and turnips should never be sown in any but a manured soil. If, on the other hand, the land is not manured, sow wheat there in preference to barley. The same, too, with fallow lands; though in these it is generally recommended that beans should be sown. It should be remembered, however, that wherever beans are sown, the land should have been manured at as recent a period as possible. If it is intended to crop ground in autumn, care must be taken to plough in manure in the month of September, just after rain has fallen. In the same way, too, if it is intended to sow in spring, the manure should be spread in the winter. It is the rule to give eighteen cart-loads of manure to each jugerum, and to spread it well before ploughing it in, or sowing the seed. If this manuring, however, is omitted, it will be requisite to spread the land with aviary dust just before hoeing is commenced. To clear up any doubts with reference to this point, I would here observe that the fair price for a cart-load of manure is one denarius; where, too, sheep furnish one cart-load, the larger cattle should furnish ten: unless this result is obtained, it is a clear proof that the husbandman has littered his cattle badly.

  There are some persons who are of opinion that the best method of manuring land is to pen sheep there, with nets erected to prevent them from straying. If land is not manured, it will get chilled; but if, on the other hand, it is over-manured, it becomes burnt up: it is a much better plan, too, to manure little and often than in excess. The warmer the soil is by nature, the less manure it requires.

  HOW TO ASCERTAIN THE QUALITY OF SEED.

  The best seed of all is that which is of the last year’s growth. That which is two years old is inferior, and three the worst of all — beyond that, it is unproductive. The same definite rule which applies to one kind of seed is applicable to them all: the seed which falls to the bottom on the threshing-floor, should be reserved for sowing, for being the most weighty it is the best in quality: there is no better method, in fact, of ascertaining its quality. The grains of those ears which have intervals between the seed should be rejected. The best grain is that which has a reddish hue, and which, when broken between the teeth, presents the same colour; that which has more white within is of inferior quality. It is a well-known fact that some lands require more seed than others, from which circumstance first arose a superstition that exists among the peasantry; it is their belief that when the ground demands the seed with greater avidity than usual, it is famished, and devours the grain. It is consistent with reason to put in the seed where the soil is humid sooner than elsewhere, to prevent the grain from rotting in the rain: on dry spots it should be sown later, and just before the fall of a shower, so that it may not have to lie long without germinating and so come to nothing. When the seed is put in early it should be sown thick, as it is a considerable time before it germinates; but when it is put in later, it should be sown thinly, to prevent it from being suffocated. There is a certain degree of skill, too, required in scattering the seed evenly; to ensure this, the hand must keep time with the step, moving always with the right foot. There are certain persons, also, who have a secret method of their own, having been born with a happy hand which imparts fruitfulness to the grain. Care should be taken not to sow seed in a warm locality which has been grown in a cold one, nor should the produce of an early soil be sown in a late one. Those who give advice to the contrary have quite misapplied their pains.

  WHAT QUANTITY OF EACH KIND OF GRAIN IS REQUISlTE FOR SOWING A JUGEBRUM.

  In a soil of middling quality, the proper proportion of seed is five modii of wheat or winter-wheat to the jugerum, ten of spelt or of seed-wheat — that being the name which we have mentioned as being given to one kind of wheat — six of barley, one-fifth more of beans than of wheat, twelve of vetches, three of chick-pease, chicheling vetches, and pease, ten of lupines, three of lentils — (these last, however, it is said, must be sown with dry manure) — six of fitches, six of fenugreek, four of kidney-beans, twenty of hay grass, and four sextarii of millet and panic. Where the soil is rich, the proportion must be greater, where it is thin, less.

  There is another distinction, too, to be made; where the soil is dense, cretaceous, or moist, there should be six modii of wheat or winter-wheat to the jugerum, but where the land is loose, dry, and prolific, four will be enough. A meagre soil, too, if the crop is not very thinly sown, will produce a diminutive, empty ear. Rich lands give a number of stalks to each grain, and yield a thick crop from only a light sowing. The result, then, is, that from four to six modii must be sown, according to the nature of the soil; though there are some who make it a rule that five modii is the proper proportion for sowing, neither more nor less, whether it is a densely-planted locality, a declivity, or a thin, meagre soil. To this subject bears reference an oracular precept which never can be too carefully observed— “Don’t rob the harvest.” Attius, in his Praxidicus, has added that the proper time for sowing is, when the moon is in Aries, Gemini, Leo, Libra, and Aquarius. Zoroaster says it should be done when the sun has passed twelve degrees of Scorpio, and the moon is in Taurus.

  THE PROPER TIMES FOR SOWING.

  We now come to a subject which has been hitherto deferred by us, and which requires our most careful attention — the proper times for sowing. This is a question that depends in a very great degree upon the stars; and I shall therefore make it my first care to set forth all the opinions that have been written in reference to the subject. Hesiod, the first writer who has given any precepts upon agriculture, speaks of one period only for sowing — the setting of the Vergiliæ: but then he wrote in Bœotia, a country of Hellas, where, as we have already stated, they are still in the habit of sowing at that period.

  It is generally agreed by the most correct writers, that with the earth, as with the birds and quadrupeds, there are certain impulses for reproduction; and the epoch for this is fixed by the Greeks at the time when the earth is warm and moist. Virgil says that wheat and spelt should be sown at the setting of the Vergiliæ, barley between the autumnal equinox and the winter solstice, and vetches, kidney-beans, and lentils at the setting of Boötes: it is of great importance, therefore, to ascertain the exact days of the rising and setting of these constellations, as well as of the others. There are some, again, who recommend the sowing to be done before the setting of the Vergiliæ, but only in a dry soil, and in those provinces where the weather is hot; for the seed, they say, if put in the ground will keep, there being no moisture to spoil it, and within a single day after the next fall of rain, will make its appearance above ground. Others, again, are of opinion that sowing should begin about seven days after the setting of the Vergiliæ, a period which is mostly followed by rain. Some think that cold soils should be sown immediately after the autumnal equinox, and a warm soil later, so that the blade may not put forth too luxuriantly before winter.

  It is universally agreed, however, that the sowing should not be done about the period of the winter solstice; for this very good reason — the winter seeds, if put in before the winter solstice, will make their appearance above ground on the seventh day, whereas, if they are sown just after it, they will hardly appear by the fortieth. There are some, however, who begin very early, and have a saying to justify their doing so, to the effect that if seed sown too early often disappoints, seed put in too late always does so. On the other hand, again, there are some who maintain that it is better to sow in spring than in a bad autumn; and
they say that if they find themselves obliged to sow in spring, they would choose the period that intervenes between the prevalence of the west winds and the vernal equinox. Some persons, however, take no notice of the celestial phenomena, and only regulate their movements by the months. In spring they put in flax, the oat, and the poppy, up to the feast of the Quinquatria, as we find done at the present day by the people of Italy beyond the Padus. There, too, they sow beans and winter-wheat in the month of November, and spelt at the end of September, up to the ides of October: others, however, sow this last after the ides of October, as late as the calends of November.

  The persons who do this take no notice, consequently, of the phænomena of Nature, while others, again, lay too much stress upon them, and hence, by these refined subtleties and distinctions, only add to their blindness; for here are ignorant rustics, not only dealing with a branch of learning, but that branch astronomy! It must still, however, be admitted that the observation of the heavens plays a very important part in the operations of agriculture; and Virgil, we find, gives it as his advice, that before any thing else, we should learn the theory of the winds, and the revolutions of the stars; for, as he says, the agriculturist, no less than the mariner, should regulate his movements thereby. It is an arduous attempt, and almost beyond all hope of success, to make an endeavour to introduce the divine science of the heavens to the uninformed mind of the rustic; still, however, with a view to such vast practical results as must be derived from this kind of knowledge, I shall make the attempt. There are some astronomical difficulties, however, which have been experienced by the learned even, that ought to be first submitted for consideration, in order that the mind may feel some encouragement on abandoning the study of the heavens, and may be acquainted with facts at least, even though it is still unable to see into futurity.

  ARRANGEMENT OF THE STARS ACCORDING TO THE TERRESTRIAL DAYS AND NIGHTS.

  In the first place, it is almost an utter impossibility to calculate with a fair degree of accuracy the days of the year and the movements of the sun. To the three hundred and sixty-five days there are still to be added the intercalary days, the result of the additional quarters of a day and night: hence it is, that it is found impossible to ascertain with exactness the proper periods for the appearance of the stars. To this we must add, too, a certain degree of uncertainty connected with these matters, that is universally admitted; thus, for instance, bad and wintry weather will often precede, by several days, the proper period for the advent of that season, a state of things known to the Greeks as προχειμάζειν; while at another time, it will last longer than usual, a state of circumstances known as ἐπιχειμάζειν. The effects, too, of the changes that take place in the seasons will sometimes be felt later, and at other times earlier, upon their reaching the face of the earth; and we not unfrequently hear the remark made, upon the return of fine weather, that the action of such and such a constellation is now completed. And then, again, as all these phænomena depend upon certain stars, arranged and regulated in the vault of heaven, we find intervening, in accordance with the movements of certain stars, hailstorms and showers, themselves productive of no slight results, as we have already observed, and apt to interfere with the anticipated regular recurrence of the seasons. Nor are we to suppose that these disappointments fall upon the human race only, for other animated beings, as well as ourselves, are deceived in regard to them, although endowed with even a greater degree of sagacity upon these points than we are, from the fact of their very existence depending so materially upon them. Hence it is, that we sometimes see the summer birds killed by too late or too early cold, and the winter birds by heat coming out of the usual season. It is for this reason, that Virgil has recommended us to study the courses of the planets, and has particularly warned us to watch the passage of the cold star Saturn.

  There are some who look upon the appearance of the butterfly as the surest sign of spring, because of the extreme delicacy of that insect. In this present year, however, in which I am penning these lines, it has been remarked that the flights of butterflies have been killed three several times, by as many returns of the cold; while the foreign birds, which brought us by the sixth of the calends of February every indication of an early spring, after that had to struggle against a winter of the greatest severity. In treating of these matters, we have to meet a twofold difficulty: first of all, we have to ascertain whether or not the celestial phænomena are regulated by certain laws, and then we have to seek how to reconcile those laws with apparent facts. We must, however, be more particularly careful to take into account the convexity of the earth, and the differences of situation in the localities upon the face of the globe; for hence it is, that the same constellation shows itself to different nations at different times, the result being, that its influence is by no means perceptible everywhere at the same moment. This difficulty has been considerably enhanced, too, by various authors, who, after making their observations in different localities, and indeed, in some instances, in the same locality, have yet given us varying or contradictory results.

  There have been three great schools of astronomy, the Chaldæan, the Ægyptian, and the Grecian. To these has been added a fourth school, which was established by the Dictator Cæsar among ourselves, and to which was entrusted the duty of regulating the year in conformity with the sun’s revolution, under the auspices of Sosigenes, an astronomer of considerable learning and skill. His theory, too, upon the discovery of certain errors, has since been corrected, no intercalations having been made for twelve successive years, upon its being found that the year which before had anticipated the constellations, was now beginning to fall behind them. Even Sosigenes himself, too, though more correct than his predecessors, has not hesitated to show, by his continual corrections in the three several treatises which he composed, that he still entertained great doubts on the subject. The writers, too, whose names are inserted at the beginning of this work, have sufficiently revealed the fact of these discrepancies, the opinions of one being rarely found to agree with those of another. This, however, is less surprising in the case of those whose plea is the difference of the localities in which they wrote. But with reference to those who, though living in the same country, have still arrived at different results, we shall here mention one remarkable instance of discrepancy. Hesiod — for under his name, also, we have a treatise extant on the Science of the Stars — has stated that the morning setting of the Vergiliæ takes place at the moment of the autumnal equinox; whereas Thales, we find, makes it the twenty-fifth day after the equinox, Anaximander the twenty-ninth, and Euctemon the forty-eighth.

  As for ourselves, we shall follow the calculations made by Julius Cæsar, which bear reference more particularly to Italy; though at the same time, we shall set forth the dicta of various other writers, bearing in mind that we are treating not of an individual country, but of Nature considered in her totality. In doing this, however, we shall name, not the writers themselves, for that would be too lengthy a task, but the countries in reference to which they speak. The reader must bear in mind, then, that for the sake of saving space, under the head of Attica, we include the islands of the Cyclades as well; under that of Macedonia, Magnesia and Thracia; under that of Egypt, Phœnice, Cyprus, and Cilicia; under that of Bœotia, Locris, Phocis, and the adjoining countries; under that of Hellespont, Chersonesus, and the contiguous parts as far as Mount Athos; under that of Ionia, Asia and the islands of Asia; under that of Peloponnesus, Achaia, and the regions lying to the west of it. Chaldæa, when mentioned, will signify Assyria and Babylonia, as well.

  My silence as to Africa, Spain, and the provinces of Gaul, will occasion no surprise, from the fact that no one has published any observations made upon the stars in those countries. Still, however, there will be no difficulty in calculating them, even for these regions as well, on reference being made to the parallels which have been set forth in the Sixth Boo
k. By adopting this course, an accurate acquaintance may be made with the astronomical relations, not only of individual nations, but of cities even as well. By taking the circular parallels which we have there appended to the several portions of the earth respectively, and applying them to the countries in question, that are similarly situate, it will be found that the rising of the heavenly bodies will be the same for all parts within those parallels, where the shadows projected are of equal length. It is also deserving of remark, that the seasons have their periodical recurrences, without any marked difference, every four years, in consequence of the influence of the sun, and that the characteristics of the seasons are developed in excess every eighth year, at the revolution of every hundredth moon.

  THE RISING AND SETTING OF THE STARS.

  The whole of this system is based upon the observation of three branches of the heavenly phænomena, the rising of the constellations, their setting, and the regular recurrence of the seasons. These risings and settings may be observed in two different ways: — The stars are either concealed, and cease to be seen at the rising of the sun, or else present themselves to our view at his setting — this last being more generally known by the name of “emersion” than of “rising,” while their dis- appearance is rather an “occultation” than a “setting.” — Considered, again, in another point of view, when upon certain days they begin to appear or disappear, at the setting or the rising of the sun, as the case may be, these are called their morning or their evening settings or risings, according as each of these phenomena takes place at day-break or twilight. It requires an interval of three quarters of an hour at least before the rising of the sun or after his setting, for the stars to be visible to us. In addition to this, there are certain stars which rise and set twice. All that we here state bears reference, it must be remembered, to the fixed stars only.
